Fig. 2.

Expression of Zmetr2b and Zmers1b confers ethylene insensitivity in light-grown Arabidopsis seedlings. In (A), the same lines used in Fig. 1 were germinated in the light for 10 days on media in the presence or absence of 20 μM ACC. One representative seedling is shown for each line. In (B), qPCR analysis of leaf and root tissue of light-grown seedlings of lines T:Zmetr2b L9 and T:Zmers1b L11. The level of expression of each transgene in leaves was set to a value of one and transgene expression in roots is shown relative to that in leaves
